Moreover it musts be connected to the barrier with the SMA transition. Fig. 5: Top view of the post template position and possible errors. Copyright 2016, Industry A.M.S. srl 7

2.4 Installation procedure SMA End Terminals can be installed in soil and/or on asphalt. It is mandatory that the ground class is between 3 and 5 according to the Soil Condition Classification DIN 18300. Before starting the installation, it is required to: adequately level the ground; secure the working zone; provide safety equipment; set-up Traffic Management system. If the ground conditions are too soft or there are services in the installation line, proceed as described in Appendix A. If rock is encountered in the subsoil during the works, Industry A.M.S. suggests to proceed as indicated at Paragraph 2.5. Ramming the posts Please ram the posts in the sequence as indicated in the pictures Fig. 2-3 (optionally it is possible to follow the procedure as described at par. 2.5). You can find a video of the installation procedure on our Youtube channel SMA Road Safety at the following link: https://www.youtube.com/watch?v=vwh0rry8skg&feature=youtu.be Fig. 6: Installation plate Fig. 7: Template for positioning the installation plates. 8 Copyright 2016, Industry A.M.S. srl

Fig. 8: Positioning of the installation plates by using the template for SMA T2-SMA T4 1. Place the installation plates (Fig. 6) on the ground in front of the barrier. The plates must be placed according to the post spacing as indicated by the green line in Fig. 2-3. 2. Screw the couple of brackets 1 (Fig. 7) to the installation plates as shown in Fig. 8. 3. Drive the post no.1 into the ground through the hole of the installation plate with the post driver (Fig.9). To avoid damage to the post, it is recommended to use the adaptor for the post driver 2. It is inserted into the pile driver and screwed on the plate of the post to be rammed. This tool can be supplied by Industry AMS srl (Fig. 10). Fig. 9: Driving of the post type IPE 80 with welded plate. Fig. 10: Tool for the post driver screwed onto the post 1 The brackets are supplied on request by Industry A.M.S. 2 The adaptor for the pile driver is supplied on request by Industry A.M.S. Copyright 2016, Industry A.M.S. srl 9

It is compulsory that the post is in a vertical position during the ramming (Fig. 11). Fig. 11: Check with a spirit level The post must be driven into the soil as deep as the upper plate on the post so that it is at the same level as the ground. (Fig. 12). Fig. 12: Ramming complete 4. Proceed with the insertion of the posts numerically next to the no. 1 as in Fig. 3-4. 5. Unscrew the brackets from the installation plates. 6. Clean the plates from dusts and debris before connecting the SMA End Terminal 10 Copyright 2016, Industry A.M.S. srl

Fixing of End Terminal and Transition M10 screws M16 screws Fig. 13: The Trolley is slid forward along the rail to permit the fixing of the installation plates. Fig. 14: Top view of the End terminal without the Trolley. Fig. 15: Side view of the End terminal installed on the soil 7. Unscrew the 4 no. M10 bolts of the Trolley in the frontal holes, then remove it by sliding it long the rail with the support of a handling device (Fig. 13-14). Copyright 2016, Industry A.M.S. srl 11

8. Fix the SMA End Terminal on the post plates and screw the M16 screws to the plate with a tightening torque of min. 90Nm and max 210Nm (class 8.8). The last inclined element behind the backstop does not need to be anchored to the soil. 9. Replace the Trolley and tighten the M10 screws with a tightening torque of min. 41 and max. 60 Nm. 10. Place the End terminal transition piece in order to connect the back-up to the barrier (see par. 2.7). 11. Fix the transition piece (see par. 2.7) with M16 bolts, tightening torque 90-210Nm ( class 8.8). In case of double sided transitions, the same procedure applies to both sides. 2.5 Installation in harder soil conditions If the ground is too hard to drive the posts with the pile driver (ground classes 6 and 7), it is necessary to use a different installation procedure. This procedure can also be used as optional to the standard procedure. 1. Drill the ground with a drill or DHT hammer for the post insertion (depth 1 m. Ø 120 mm) 2. Place the installation plates beside the holes. 3. Fill the holes with concrete R 25 Mpa. CK 4. Insert the post and ensure that the post plate is at ground level. 5. Wait for the concrete cure time and make sure the post plates are clean. 6. Proceed as described at paragraph 2.7. Fig. 16: The picture shows the post insertion of the SMA T 4 after filling in the concrete.. 12 Copyright 2016, Industry A.M.S. srl

2.6 Solution for working zones The SMA End Terminal can also be used as a temporary re-directive solution for working zones (Fig. 16). In this case, the SMA device is fixed on a steel plate which is positioned in front of the obstacle without drilling the ground. Fig. 17: SMA temporary solution for working zones The device is supplied already mounted on the steel plate, so the installation procedure is very simple and fast: 1) Place the End Terminal for working zones in front of the obstacle. 2) Fix the End Terminal to the obstacle with a suitable connection. After the road works, it is possible to unscrew the connection and remove the SMA End Terminal by lifting it from the ground. Copyright 2016, Industry A.M.S. srl 13

2.7 Installation of the standard Transition Piece The transition piece will be supplied according to the barrier specifications. The customer has to advise the following information: - Beam profile of the barrier system; - Height from the ground; - Dynamic deflection; - Position of the bolt holes on the beam profile; - Connection side of the barrier (Fig. 15) Fixing procedure 1. Match the holes on the transition with the holes on the end/begin of the barrier 2. Screw the transition to the end/begin of the barrier by mean of M16 bolts, with a tightening torque of min. 90Nm and max 210 Nm (bolts class 8.8). Fig.18: Top view of the End Terminal connected to the barrier. Fig. 19: Example of standard transition piece to two wave beam barrier Fig. 20: Example of transition piece to three wave beam barrier 14 Copyright 2016, Industry A.M.S. srl

Fig. 21: Example of transition piece to concrete barrier. 2.8 Crash test on the transition The SMA End terminal has been tested according to the standard EN 1317 by using a Transition Section between the safety barrier system and the terminal. For the Crash test TT 6.3.110 the End Terminal has been connected to the barrier Marcegaglia N2W2. Such barrier has performed the crash test TB11 with the following results. Tab 3: Test results of the Crash Test TB11 on the 2 wave side N2W2 Guardrail manufactured by Marcegaglia. Test Facility Type Barrier length m Mass kg Speed km/h ASI max 1.4 D m W m TB32 Aisico Side 20 84 1.500 110 1=A 0,7 0,8=W2 TB11 Aisico Side 20 84 900 100 0,9=A 0,6 0,7=W2 The results of the Crash test on the End terminal are indicated in Tab. 1 at the paragraph 1.2. According to the draft FprEN1317-7:2014 the SMA End terminal can be connected to each type of N2W2 barrier without the any requirement of further tests. In fact, at the paragraph 5 of the draft FprEN1317-7:2014 it is explained as follows: After a successful test with Approach 6, the Approach 6 test shall not be repeated if the terminal is connected to a barrier with a lower dynamic deflection (in the EN1317-2 TB11 test), but shall be retested with Approach 6 if connected to a barrier with a greater dynamic deflection (in the EN1317-2 TB11 test). If the difference between the two dynamic deflections is less than 20%, the Approach 6 test shall not be performed with the barrier with a greater dynamic deflection.

2.9 Transition Section and Installation The Transition Section consists of 8m of an N2W2 barrier system. (Fig.22 & 23). The 4m section at the terminal end is sloped down to connect with the backstop of the terminal by means of a connection piece. Industry A.M.S. does not supply this Transition Section but only the component which connects the End Terminal and the barrier (Fig. 24). If the existing barrier has a Working Width higher than W2, the installer must fit appropriate transition sections between the different Working Widths as per the manufacturers recommendations or local standards. In the example below (Fig. 22 & 23) the last section of the transition barrier is sloped down.
